Avian Nutrition Basics

This 1-hour, R.A.C.E.-approved webinar recording is designed to impart a basic understanding of avian nutrition for the veterinary health professional as well as students in these fields. Viewing of this recorded is strongly recommended before viewing the recording of the live webinar event Clinical Avian Nutrition for Veterinary Health Professionals by Susan Orosz, PhD, DVM, DABVP (Avian Practice), DECZM.

Parenteral Nutrition in Birds

If the gut works, use it. The preferred route for providing nutrition is enteral feeding since this preserves intestinal structure and function. Parenteral nutrition is indicated to prevent malnutrition when patients cannot consume adequate nutrients by oral feeding or tube feeding or when the respiratory tract cannot be protected. Parenteral nutrition is 100% bioavailable since nutrients reach tissue without the variations associated with gastrointestinal digestion.

Nutritional Management of Renal Disease in Birds

There are a number of potential nutritional problems that can promote renal disease. Excess dietary protein, excess dietary calcium, hypovitaminosis A, or hypervitaminosis D may lead to nephritis or other degenerative renal changes…

Nutritional Management of Liver Disease in Birds

In mammals, chronic liver disease is often associated with decreased intake of food, mainly due to anorexia, nausea, and vomiting, as well as taste abnormalities, and the same appears to be true for the avian patient. Chronic liver disease may also lead to maldigestion and malabsorption, as well as metabolic abnormalities such as increased protein and lipid catabolism, glucose intolerance, depletion of hepatic glycogen stores, and decreased glucose oxidation. Therefore chronic liver disease may lead to significant malnutrition and weight loss, particularly in patients with severe hepatic dysfunction…

Expert Panel on Companion Bird Nutrition

In 1998, an expert committee met to discuss the nutritional needs of companion birds. The purpose of the meeting was to discuss and develop nutrient profiles for companion birds, focusing on profiles for formulated feed.

The expert panel developed maintenance guidelines for two broad groups of birds: psittacines and passerines (regardless of size or genus). These conservative, generalized guidelines are extrapolated from the National Research Council requirements for poultry and…

Avian Hematology and Biochemistry Panels

Although hematology and biochemistry are an important part of the clinical picture in the avian patient, this bloodwork remains just ‘part of the picture’. All too often, when a clinician is unfamiliar with a species, the reaction is often to rely on laboratory results to hang a diagnosis upon. Although we have all been guilty of this, such an approach is inappropriate. For each sick bird, the following diagnostic tools should be applied: complete history, visual examination of the bird and its environment, physical examination, clinical pathology sample collection (blood, feces, swabs, aspirates, etc.), and radiography.

White blood cells are similar to mammalian lines, except that mammalian neutrophils are replaced with heterophils and mammalian platelets are replaced with thromobocytes. There are significant variations in normal differentials among avian species, in particular the total white cell count and…

Avian Nutrition Glossary

Created with a focus on the bird, LafeberVet’s Nutrition Glossary is an extensive list of vocabulary terms. Listed terms range from nutrients like vitamins and minerals, nutritional strategies ranging from frugivore to fungivore, and related anatomy or physiologic terms like crop and coprodeum, and even nutrition-related diseases like goiter and gout.

Pet Food Labels: Unraveling the Fine Print

After reading label panels, owners often bring questions and concerns to veterinary staff. The pet food label is the primary means by which product information is communicated from the manufacturer or distributor to pet owners, veterinary health care team members, and regulatory officials. Reading and interpreting pet food labels is one method that healthcare team members and pet owners can obtain information about pet foods. However, it is important to remember that pet food labels do not necessarily provide information about…

The Nutritional Content of Pet Bird Diets

Little is known about the nutritional requirements of companion bird species. Dietary recommendations for pet birds are extrapolated from domestic poultry nutritional requirements; however these parameters are generally calculated to minimize cost while maximizing meat and egg production.

Clinical Perspectives on the Principles of Avian Nutrition

The types of foodstuffs consumed in the wild are often used to classify the nutritional requirements for groups of animals. Usually birds within the Order Psittaciformes are considered to consume plant-based foodstuffs and are classified as florivores. Subdivisions within this category include granivores (budgies and cockatiels), frugivores (many of the macaws), and nectarivores (lorikeets and lories). Yet these artificial lines are sometimes too simplistic, as many psittacine birds cross over a category to consume a larger variety of foodstuffs…
